ABSTRACT:
A rapid gravity downflow filtration system applicable to a bank of several filters in which filtered water for backwashing is stored at a relatively high level in a common washwater storage compartment serving all filters and in which the filtered water for backwashing is delivered to it's storage by gravity using the surplus operating head available at the beginning of the filter operating cycle for the purpose thereby entirely eliminating the necessity for powered motivation of backwash water flow during backwashing, or, in alternative filter systems in which the backwash water flow is motivated by displacement with compressed air, reducing the power requirement.
